Application filed May 10, 1920, Serial No. 380,354. Renewed larch 3, 1921.

To all whom it may concern:

Be it known that I, J OHN K. BLnAoKAonn, a citizen of the United States, residing at Bloomer, in the county of Chippewa and State of Wisconsin, have invented certain new and useful Improvements in Window- Fasteners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved window fastener and one object of the invention is to provide a fastener so constructed that it may be embedded in a wall formed of cement or other plastic adjacent a window and the locking arm readily swung into position fo engaging the sash and securing the sash against movement.

Another object of the invention is to so construct this fastener that the locking arm may be easily removed from the socket when desired but so associated with the socket that it will not accidentally come out of proper engagement with the socket.

Another object of the invention is to so construct the fastener that the locking arm may be removed from the socket with the socket still embedded in a wall and thus permitting the securing arm to be removed and a new one put in place in case it should become broken.

Another object of the invention is to so contruct the device that the socket may be cast in a single piece and the locking arm also formed by casting thus permitting the lock to be easily and cheaply produced. This invention is illustrated in the accompanying drawings wherein- Figure 1 is a transverse sectional view through a window structure showing the improved looking devices in place and in operative engagement with window sashes.

Fig. 2 is a view taken along the line 2-2 of Fig. 1 and showing the window sash in section and the fastening device elevation.

This fastener is used for locking a window sash 1 against sliding movement and includes a socket element 2 which will be embedded in the wall 3 adjacent the window and a securing arm 4; which will be removably and pivotally connected with the socket. The socket is in the form of a hollow housing and is provided adjacent its inner end with side extensions or wings 5 which will serve as anchoring means to retain the Specification of Letters latent.

socket in the wall. 1 It is, of course, obvious that when the socket is put in place it must be inserted while the cement is soft and the cement allowed to set about the socket. The outer wall of this socket is provided with a key-hole opening 6 having the enlarged end 6' at the upper end as shown in Fig. 2. The securing arm 4 is provided with an enlarged head 7 for engaging the window sash 1 and at its opposite end provided with an inwardly extending stem 8 which extends through the slot 6 and is provided with a head 9 which is of sufficient size to pass through the enlargement 6' of the slot 6. Therefore, the head 9 may be passed through the enlargement 6 and the securing arm moved downwardly with the stem 8 positioned in the slot 6. In this position the securing arm may be swung to engage the window sash and the teeth of the head will bite into the sash and prevent the head from slipping upon the window sash. Therefore, the window may be raised a desired amount and when the securing arm is swung to the operative position the window will be held in this position. If the securing arm should become broken in any way or the teeth should need re-sharpening, the securing arm can be easily removed by drawing it upoutwardly through the enlarged end portion of the slot. The necessary repair can then be made and this securing arm or a new one put back in place. It has been stated that this fastener will be used in connection with a window sash but it is to be understood that it can be used for securing a sliding door or any other similar device.

I claim:

1. A window fastener comprising a socket member having an outer wall provided with a key-hole slot with its enlargement at its upper end, a securing arm having a stem extending through the key-hole slot and an enlarged head carried by the stem and passing through the enlarged end portion of the slot to releasably and pivotally mount the arm.

2. A window fastener comprising a socket member adapted for embedding in a plastic support and enlarged toward its inner end, the socket member having an outer wall provided with a longitudinally extended slot terminating in an enlarged upper end portion, a securing arm having a stem extending through the slot to pivotally and slidably mount the arm, and an enlarged head carried by the stem end portion, within the socket member. r

3. A window fastener comprising a socket member, including a plate having a key-hole opening formed therein, and a securing arm having at one end an enlarged head pro vided with gripping teeth and at its opposite end a stem extending through the slot and terminating in a head releasably holding the arm in engagement with the plate.

1. A windowfastener comprising a socket member including a plate having an opening formed therein enlarged toward one end,

7 and a securing arm having window gripping my hand.
